Background: Gastrin is an early incretin candidate, since it is released by oral glucose and potentiates the glucose-induced insulin secretion. It has been shown that only in hypoglycaemic or hyperglycaemic conditions gastrin release is influenced by changes in blood glucose and insulin concentrations.Aim: To evaluate whether there is a relation between fasting serum glucose and serum gastrin concentrations.Methods: Gastrin and glu...

Introduction: The cytokine tumor necrosis factor alpha (TNFα) is encoded by the TNFα gene and stimulates bone resorption. TNFα is involved in the pathogenesis of bone loss associated with estrogen deficiency. Polymorphisms in the TNFα gene have been associated with bone mineral density (BMD) in different populations.Objectives: The present study aimed to explore the influence of the single-nucleotide polymorphism <em...

Background: Excessive level of cortisol in patients with Cushing’s disease (CD) can cause an immunosuppression. Therefore after resolution of hypercorticism the underline autoimmune disorders can appears.Aim: We are presenting three cases of autoimmune disorders diagnosed in patients successfully treated for CD.Results: Case 1: Woman, 37-year-old with confirmed panhypopituitarism after transsphenoidal adenomectomy (TSA) for CD...

Background: The expression and/or co-expression of somatostatin (sstr1–5) and dopamine (DR) receptors in neuroendocrine tumors (NETS) is of clinical interest as their expression implies that NETS could be treated with combined targeted therapy. In addition, the expression of sstrs permits tumour visualization with radiolabelled sst analogs (111In-DTPA-OctreoScan).Methods: We analyzed preoperative Octreoscans findings (also graded for the ...

Objectives: In familial MTC there is genotype-phenotype correlation. The phenotype and clinical outcome in exon8 (G533C) carriers has not been well established.Methods: 95 patients operated for familial MTC (27.2% males) were followed for 0.9–30 years (mean 8.0, median 5.5 years). 45.3% (n=43) were exon8 carriers (exon8MTC) and the remaning were non-exon8MTCs (n=52, exons 10, 11, 13, 14, and 16). Pre-, postoperative calcitonin, ext...

Metabolic syndrome (MS) is an important etiologic risk factor for the development and progression of certain cancers, including colorectal. Bile acids (BA) are potent antimicrobials that support gastrointestinal health and the dysregulation of BA homeostasis is thought to contribute to gut dysbiosis and drive endotoxemia. Furthermore, an increase in the cytotoxicity ofintestinal BA species can directly damage enterocytes and promote carcinogenesis. We have previously shown tha...

Psoriasis patients have an increased risk of cardiovascular disease, stroke, hypertension, and type 2 diabetes (T2D). External factors (infections, stress, trauma, endocrine diseases) can trigger psoriasis. Skin diseases in patients with T2D are increased, hyperglycemia leads to damage to vascular intima. Itching of the skin leads to disruption of the repair and regeneration.Objective: To study the influence of T2D on the exacerbations of psoriasis.<...

Introduction: Betamethasone (BM) is widely used in pregnancy. Its diabetogenic potential is known, and in combination with placental insulin resistance in pregnancy, leads to a transient increase in glycemia. Our aim was to study the changes in glycemia in women with singleton pregnancies and pre-existing diabetes mellitus, under insulin therapy, after administration of BM for obstetric causes.Materials and methods: We closely monitored and assessed the ...

The health burden associated with non-alcoholic fatty liver disease (NAFLD), the hepatic manifestation of the metabolic syndrome, continues to escalate. Not only is NAFLD associated with significant liver-specific and cardiovascular morbidity and mortality, but patients are at risk of the development of hepatocellular carcinoma (HCC); a malignancy where the incidence continues to rise and there are very limited therapeutic strategies.Aldo-keto reductase ...

Background: Plasma microRNAs (miRs) (miR-4446-3p, miR-215-5p, miR-342-5p) were downregulated in patients with active acromegaly (AM) compared with healthy control subjects as assessed by next-generation sequencing.Aim: The aim of this study wasto validate the previously observed finding in the newly enrolled patients with AM using qRT-PCR.Materials and methods: Morning plasma samples were collected from fasting patients with AM and...
